A Trial of Intratumoral Injections of SD-101 in Combination With Pembrolizumab in Patients With Metastatic Melanoma or Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma

12. juli 2021 opdateret af: Dynavax Technologies Corporation

A Phase 1b/2, Open-label, Multicenter, Dose-escalation and Expansion Trial of Intratumoral SD-101 in Combination With Pembrolizumab in Patients With Metastatic Melanoma or Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma (SYNERGY-001)

This is a phase 1b/2, open-label, multicenter trial designed to evaluate the safety, tolerability, biologic activity, and preliminary efficacy of intratumoral SD-101 injections in combination with intravenous pembrolizumab in patients with metastatic melanoma or recurrent or metastatic head and neck squamous cell carcinoma (HNSCC).

This study will be conducted in 2 phases. Phase 1 evaluates SD-101 given in combination with pembrolizumab in melanoma populations (anti-PD-1/L1 naïve and anti-PD-1/L1 experienced with progressive disease) in up to 4 Dose Escalation cohorts to identify a recommended Phase 2 dose (RP2D) to be evaluated in up to 4 Dose Expansion cohorts in Phase 2. Phase 2 also includes up to 4 Dose Expansion cohorts of patients with HNSCC (anti-PD-1/L1 naïve and anti-PD-1/L1 experienced with progressive disease).

  5. Have provided 2 tissue biopsy samples taken of the target lesion (Lesion A) as a single biopsy split into 2 samples or 2 separate biopsies that meet the minimal sample size requirement per the study laboratory manual. One sample is for determining PD-L1 expression level by immunohistochemistry and can be an archival sample of the anticipated target lesion that has been collected within 3 months of screening. The other sample is for RNA expression profiling and must be a fresh biopsy.
  6. Life expectancy of at least 6 months

  7. Female patients of childbearing potential, as defined in Section 5.2.1, must have a negative urine or serum pregnancy test within 72 hours prior to taking the first dose of trial treatment.

The 2 medically acceptable birth control methods can be either 2 barrier methods or a barrier method plus a hormonal method to prevent pregnancy. The following are considered adequate barrier methods of contraception: diaphragm, condom (by the partner), copper intrauterine device, sponge, or spermicide as per local regulations or guidelines. Appropriate hormonal contraceptives will include any registered and marketed contraceptive agent that contains an estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or intramuscular agents).

    Male patients of reproductive potential, as described in Section 5.2.1, must agree to use an adequate method of contraception from Day 1 through 120 days after the last dose of trial treatment.

    Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the patient.

The target lesion should be of sufficient size such that the required tumor biopsies do not significantly affect tumor assessment per RECIST v1.1. If superficial, the target lesion must measure at least 10 mm in diameter, be measured by calipers, and be documented photographically. Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-regional therapy, are usually not considered measurable unless there has been demonstrated progression in the lesion. Approval from the Medical Monitor is required to inject a previously radiated lesion.

  15. Must have at least 1 lesion that qualifies as a target lesion per RECIST v1.1, and which must be easily accessible (palpable or can be visualized by ultrasound) and amenable to multiple intratumoral injections. The target lesion should be of sufficient size such that the required tumor biopsies do not significantly affect tumor assessment per RECIST v1.1. Tumor lesions situated in a previously irradiated area, or in an area subjected to other loco-regional therapy, are usually not considered measurable unless there has been demonstrated progression in the lesion. Approval from the Medical Monitor is required to inject a previously radiated lesion.
  16. Expansion Cohort 4: Must have documented confirmed PD per RECIST v1.1 on a prior treatment regimen containing an anti-PD-1/L1 drug (see Appendix 6 for definition of PD per RECIST v1.1)

  17. Expansion Cohort 7: Must have all of the following:

    1. Received at least 2 doses of an anti-PD-1/L1 therapy, where the last dose of anti-PD-1/L1 therapy was within 6 months of study enrollment (Day 1)

  15. Known active central nervous system metastases or carcinomatous meningitis

    NOTE: Patients with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging [using the identical imaging modality for each assessment, either MRI or CT scan] for at least 4 weeks prior to the first dose of trial treatment and with any neurologic symptoms returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.

  16. Use of any investigational agent within the last 28 days prior to study enrollment
  17. Has received a live-virus vaccination within 30 days of planned treatment start. Seasonal flu vaccines that do not contain live virus are permitted.
